The operation is as follows: As the wheels 3 travel over the ground they revolve with the axle 2, and when so revolving by adjusting the sprocket-wheel 8 in engagement with the adjacent wheel 3 by any suitable clutch mechanism said s rocket-wheel 8 will also revolve and in t e same direction as the wheel 3, and as the sprocket-wheel 8 revolves the shaft 9, sprocket-wheel 11, and toothed wheel 12 are also revolved and in the same direction as said wheels 3, because the chain belt 16 communicates motion from said and the toothed wheel 12 engaging with the toothed wheel 19, fixed on shaft 17, as said toothed wheel 12 revolves the toothed wheel 17 would also be revolved, but in the opposite direction to that at which the shaft 9 is revolving, and the sprocket-wheels 20 and 21 being fixed on the shaft 17 as the latter revolves the sprocket-wheels 13 and 14, being loose on shaft 9, will also be revolved by the chain belts 23 and 24, and motion being transmitted from the sprocket-wheels 20 and 21 to the sprocketewheels 13 and 14 the latter operate in the same direction as the shaft 17, but in the opposite direction to the shaft elevating-carriers 32 bein operated by passing over the sprocket-whee fs 20 and 21,0utside of the chain belts 23 and 24, and said sprocketwheels 13 and 14 and shaft 17 operati in the same direction to the shaft 9 and'w reels 3 said carriers move in the opposite direction to that at which the machine is traveling, and the rake-heads 25, to which the raketeeth 26 are secured, being attached to the chain belts 23 and 24'as said chain belts 23 and 24 travel along the under side of the sprocket-wheels 20 and 14 and 21"and 13, respectively, said rake-teeth 26 travel over the ground in the same direction as that in which the machine is traveling, and as said teeth 26 pass over and close to the o und they gather and collectthe hay, and as saidrake-teeth travel farther onward they turn upward and deliver it onto the'endless carriers 32, on which the hay is carried upward until it comes to the roller'31, and as saidcarriers 32 pass over said roller 31- the hay falls .off said carriers and down between the teeth of the opposite sides of the frame 35. Again, when the sprocket-wheel 47 is revolvlng motion is transmitted from the sprocketsleeve 51 lengthwise on the shaft 45 until the interior conical face of the portion 53 of the conical friction-clutch engages with the exterior conical face of the portion 50 of said' friction-clutch. This holds the sleeve 51 and sprocket-wheel 52 to rotate with shaft 45. 72 designates a sprocket-wheel on tne shaft 46, and motion is communicated from the shaft 45 to the shaft 46 by a chain belt 74' passing over said sprocket-wheels 52 and 72. 73 designates another sprocket-wheel on the shaft 46, and 75 a sprocket-wheel on the shaft 40, and motion is communicated from the shaft 46 to the shaft 40 by a belt passing over said sprocketavheels 73 and 7 5, and as said shaft 40'rotates the crank-arms 4]. are also rotated, which operate the pitmen 42, and the latter being pivotally connected at one end to said crank-arm 41 and at the other end to the segmental bar 36 and the latter being pivotally connected to the frame 35 by the connecting-bars 38. As said pitmen 42 are operated the segmental bar 36 is swung or vibrated, as well as the frame 35, lengthwise of the machine, and as thehay falls down between the opposite sides of this swinging frame 35 the hay is distributed evenly and lengthwise on the teeth 807 As compresses the coil-spring 96, as follows: The chains 93 connect the cross-bar 6V, to which the teeth are rigidly secured, to the shouldered bar 90,'and the shoulder g on the shoulder'ed bar engaging with a shoulder n on ICC the hay'collects on the teeth 80 its weight the lever,97, and said lever 97 being pivotally connected to the vertical bar 94, and a block being secured to the upper end of said bar 94, and the coil-spring 96 being located between said block 95 and the cross-bar c.

mpresses the coil-spring 96. Thislowers the vertical bar 94 and teeth 80, together with the sidebars 82, connected therewith,

As -tlge. hay collects on the teeth SO its weight and as'.thespring 96 is compressed by the weight of the hay on the teeth 80 said .teeth 80 and side bars 82 thereof gradually lower,

and said side bars 82 being connected to the' connecting-bars 38 by chains 87 passing 'over pulleys 84, and one end of each of said connecting-bars being pivotally connected to the frame 35 and the bolts 39, which connect the other end of said connecting-bars 38 to the segmental bars 36 being loose and adapted to move-freely up and down in the seg- -mental slots 37 in said segmental bars 36. As

the teeth 80 and side bars 82 are lowered by the weight of the hay the ends of the connectingbars 38 are raised in the slots 37 of the segmental bars 36, and as said ends of said connecting-bars are raised the swing or vibration j on a smallerarea crosswise of the machine,

of the frame will be less because the ends of the connecting-bars 38 are gradually adjusted toward or closer to the pivot 34 on,

which said segmental bars 36' are pivoted. The result is that as the hay accumulates on the teeth 80 the swin or vibration of the frame 35 becomes less en thwise of the machine Consequently the hay is spread over a smaller space lengthwise of the teeth 80,

and the side bars 82, being-connected by the chains 86 to the outer ends of the levers 85 and the inner ends of said levers 85 abutting against the plate f of the gates 83, as the teeth 80 and side bar 82 lower they draw down on the outer end of said levers 85,

which raise the inner ends of said levers as well as the inner free ends of said gates 83. This gradually brings the inner ends of said gates83 together as the hay accumulates on the teeth 80, and as the inner ends of these gates gradually close together the hay falls the result of which, together with the lessening of the swing or vibration of the frame 35 lengthwise of the machine, is that a conical pile or cock of hay is formed'on said teeth 80,

- and the weight 98 on the lever 97 is regulated according to the" weight or quantity of hay required in the pile or cock when complete,

so that when sufficient hay has accumulated on the teeth to overcome the resistance of the weight 98 the weighted end of said lever 97 is raised and the end of said lever on which the shoulder n is formed is lowered until the shoulder g on the bar disengages therefrom, when the teeth will further lower until they rest on the ground, which action will reand rest on the ground the gates 83 are closed together at their inner ends, onto which gates when in this position the hay falls as the ma- 1 chine travelsforward after or while the pile or cook of hay is being deposited and until the machine is set or the teeth 80 adjusted in proper position to receive the hay. Just as soonas the conical pile orcock of hay has been delivered on the ground the operator in the seat 28 presses downward on the outer end of the arm 69, and this adjustment,

through the oscillating shaft 68, connectingrod 71, and lever 65,.adjusts the sleeve 62 lengthwise on the shaft 45 until tlr c exterior conical face of the portion 63 of the conical friction-clutch engages with the interior conical face e of the portion 50 of the conical friction-clutch. This holds the sleeve 62 to rotate with the shaft 45, and as said sleeve 62 rotates the chains 81, which are secured at one end to said sleeve 62 and at the other end to the cross-bar (l of the frame 77, are wound around it, which raises the rear end of the frame 77, teeth 80, side bars 82, and bar 90 until the inclined face g of the bar 90 passes the inclined face a on the lever 97 until the shoulder gof said bar 90 will engage with the shoulder 11, of the lever 97, which operation slackens the chains 86 and S7, and the slackening of the chains 86 permits the inner ends of the leve 's 85, as well as tl inner adjacent edges of the gates 83, to lower and spread apart, when the hay which has collected thereon will fall on the teeth 80, and the slackening of the chains 87 will permit the lowering of the end of the connecting-bar 38adjaccnt'to the segmental bar 36 to give a wide spread to the hay which forms the lower portion of the hay-cock, the connecting-bar 38 being of snllicient 'weight to cause it to lift the chain 87, after which the operation hereinhefore described is repeated, and so on.
